Drexel University College of Medicine Dean Daniel Schidlow announced the cuts in an email to staff Thursday morning. Drexel doctors staff many of Hahnemann's departments and wards.

"Unfortunately, the abrupt closure of Hahnemann has brought the Drexel University Physicians (DUP) practice plan to a crisis point, which has caused extremely difficult decisions to be made," Schidlow said.

The other 40% of physicians and clinical staff who are not offered positions "will be provided with severance and outplacement counseling services," according to the email.

The move comes despite previous state and city efforts to keep the medical center open. Last week, presidential candidate Vermont Sen. Bernie Sanders also weighed in, calling for Joel Freedman, the president and CEO of Philadelphia Academic Health System, which owns the hospital, to cease closure plans.

Employees at Hahnemann told NBC10 the hospital has become a "ghost town" as fewer patients have been admitted and wards closed.

On Wednesday, it stopped admitting patients from the emergency room into the hospital. Before that, it closed its maternity ward and began diverting trauma patients to other hospitals.
